Synephrine is an amine found in the Citrus aurantium fruit. This fruit has been used in Eastern medicine for hundreds of years. Synephrine can increase ones metabolic rate and thermogenesis without any side effects on blood pressure or cardiovascular health. An increased metabolic rate means more calories are burned. Synephrine’s effect on metabolic rate lies in its ability to bind to specific adrenergic receptors, the ?-1.
Get in position for a kettlebell swing, except this time, as you hike the weight back, take a small step to the right with your right leg. Shift your left leg as well. As soon as the left leg lands, forcefully drive your hips forward, initiating the kettlebell swing. Repeat the pattern, this time taking a step with your left leg. Alternate reps on both sides. Do 3 sets.
Start in plank position, shoulders directly over elbows, forearms and hands on the ground, core and glutes squeezed tight. Now lift your right arm off the ground and reach your hand forward. Pause for 1 second then return to the plank position. Repeat on the other side. Work to keep your hips as square as possible as you do this. Alternate reps on each side for 4 sets. Work for 40 seconds, then rest for 20 on each set during Week 3. During Week 4, work for 50 seconds, then rest for 10.
Also note, testosterone isn’t the only relevant sex difference here. There are sex differences in gene expression, sex differences in other anabolic hormones like IGF-1 (which may play a bigger role in women than men), and, obviously, sex differences in estrogen (which, contrary to popular belief, exerts anabolic effects in muscle tissue). Testosterone is only one piece of a much larger picture that only gets more confusing and convoluted the more you look at it. At the end of the day, it’s best to just remember the messiness of physiology and understand that outcomes (similar relative muscle growth and strength gains, supported by heaps of research) trump mechanisms (differences in testosterone levels) every time.
This video is good for starting out. I was sore after doing it but I didn't feel like i was going to keel over or anything. I mean you'll definitely grow out of this video but it's good to get your head back in the muscle building routine. I'd also recommend this for like someone in their 40's+ because it's low impact and will just help you keep your strength up.
This week you're going to continue with the circuit-style sets; this time you'll perform only 12 reps of each movement, but there are two (tough!) changes: You'll complete a total of 4 full circuits (that's four sets of each exercise for both workouts) and there will be no rest in between each circuit. This week is all about keeping you moving! After you finish the last movement of either workout, you'll immediately return to the first movement and begin a new circuit!
